International recall: Service brakes, air
What is wrong
Navistar, Inc. (Navistar) is recalling certain 2021 International LT, RH, MV, and HV vehicles equipped with Bendix pressure switches. A retainer was not properly seated in the SC-3 single check valve and may not provide source air isolation when pressure is applied. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
What could happen
Unintended spring brake application may occur, increasing the risk of a crash.
The fix
Navistar will notify owners, and dealers will replace the SC-3 check valves, free of charge. Owner notification letters were mailed on May 28, 2021. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 21503.
